  "Description": "The plsdof package provides Degrees of Freedom estimates\nfor Partial Least Squares (PLS) Regression. Model selection for\nPLS is based on various information criteria (aic, bic, gmdl)\nor on cross-validation. Estimates for the mean and covariance\nof the PLS regression coefficients are available. They allow\nthe construction of approximate confidence intervals and the\napplication of test procedures (Kramer and Sugiyama 2012\n<doi:10.1198/jasa.2011.tm10107>). Further, cross-validation\nprocedures for Ridge Regression and Principal Components\nRegression are available.",
